Patent FI-970333-A (FI)
Inventor: LYNCH TOM SADLER
IPC: A22C11/10
Filed: 1997-01-27
Abstract: A method and apparatus for crimping sausage links and ends are described. The apparatus consists of two spaced crimping devices (1), each crimping device having a pair of crimping arms (3, 4) with each of said crimping arms (3, 4) having a pair of inwardly directed crimping fingers (9, 10). The crimping fingers (9, 10) have inner surfaces (11, 15, 16, 17) which, in a first position, when the arms are separated, define a passageway through the device for receiving and supporting the filler casing. The apparatus includes fillers (5, 6) coupled to each of the pair of arms which are coupled to actuating mechanisms which act on both pairs of arms substantially simultaneously to urge the arms (3, 4) towards each other to close the passageway and crimp the filler casing and at the same time the passageways of the adjacent crimping devices are displaced radially inwards causing the filler casing between the arms to be shortened axially in length as it is being crimped.

Title: Improvements in or relating to control systems embodying electromagnetic pumps
IPC: G05D23/24
Filed: 1959-01-13
Abstract: 914,908. Automatic temperature-control systems; pumps operating by electromagnetic interaction with fluids. MINNEAPOLISHONEYWELL REGULATOR CO. Jan. 13, 1959 [Jan. 15, 1958], No. 1247/59. Classes 35 and 38 (4). The invention depends on the observation that in a pump operating by the interaction of an electric current and magnetic field in the liquid pumped, some pumping action is produced without the main magnetic field due to local flux generated by the current alone, and the main field may be applied in a sense to buck or boost this action. As shown, the principle is applied to a heating-control system in which the pressure developed in the pump duct 12 may be used to operate an actuator controlling a heating valve. For this purpose, the excitation of the pump core 10 by coils 70 is controlled by a bridge which includes a temperature-sensitive resistance 60, the steady current through the pumped liquid being supplied through electrodes 16, 17 on either side of the duct in the usual manner.

Patent GB-423823-A (GB)
Title: Improvements in the manufacture of pulverulent metal alloys
IPC: F41A23/28
Filed: 1934-01-13
Abstract: Pulverulent alloys are produced by thermally decomposing a mixture of metal carbonyls, treating the particles of the resulting metal powder with a substance hindering the frilling together of the particles or with a material which on heating will yield such a substance and then heating the powder in an inert or reducing atmosphere at temperatures to effect alloying. Nickel-iron alloys containing between 40-80 per cent of nickel, iron-nickel-cobalt alloys containing 25-50 per cent of iron, 30-60 of nickel and 15-30 of cobalt with or without up to 10 of molybdenum or tungsten and nickel-cobalt, nickel-cobalt-moly-bdenum and nickel-cobalt-tungsten alloys are referred to.  The substances added to the metal powders may comprise refractory substances, such as oxides of alkaline earth metal or aluminium or zinc, ceramic substances, silica, titanic acid or difficultly reducible or fusible compounds such as pulverized kaolin, asbestos or mica.  These substances may form coatings on the metal or metal coatings may be produced by heating the powders in air to 125-150 DEG  C., or the substances may be wetted with water and then heated to 140-175 DEG  C.  The additional substances may be removed from the powders after heating by any suitable means.  The temperatures used for the heating are preferably between 900 and 1000 DEG  C.  In an example 20 parts of a nickel-iron powder consisting of 41,8 per cent of nickel, 1,4 of carbon and the rest iron is made into a paste with a solution of 1,2 parts of aluminium nitrate in 4 parts of water.  The paste is then heated for 12 hours at 1000 DEG  C., in flowing hydrogen, the carbon content being lowered to 0,04 per cent. The frothy mass containing some aluminium oxide is ground in a ball mill, heated for about 1/2 hour at 600 DEG  C., and worked up into cores for pupin coils.

Filed: 1941-02-06
Abstract: 546,978. Artificial silk &c. ; dyeing processes. COURTAULDS, Ltd., and WORMELL, R. L. Feb. 6, 1941, No. 1579. [Classes 2 (ii) and 15 (ii)] Threads made from casein of animal or vegetable origin are subjected to a hardening treatment and are then impregnated with a solution of a normal alkali metal salt of an aliphatic dibasic acid containing at least six carbon atoms in the molecule, for a time, dependent on the temperature, sufficient to produce an improvement in the wet tenacity and other properties. The treatment also reduces the wet extensibility, and increases the fastness to washing after dyeing. The threads may be hardened by treatment with a salt such as an aluminium or chromium salt with or without formaldehyde. For the further treatment there may be used di-sodium adipate, or sebacate. The solution may also contain formaldehyde. In an example casein fibres are hardened and insolubilized by treatment with a solution containing formaldehyde and an aluminium salt. A skein of the dried fibres is wetted out with warm water and then soaked in an aqueous solution of basic chromium sulphate containing formaldehyde. After several hours treatment in the warm solution, the skein is removed, washed, and placed in a bath containing di-sodium adipate and formaldehyde. The temperature is maintained at 95‹C. for a few hours. The skein is then washed and dried.

Title: Improvements in or relating to ultra high frequency discriminator apparatus
IPC: H03D9/04
Filed: 1944-01-28
Abstract: 593,573. Frequency modulation; velocity-modulated tubes. SPERRY GYROSCOPE CO., Inc. Jan. 28, 1944, No. 1682. Convention date, Feb. 1, 1943. [Classes 39 (i) and 40 (v)] [Also in Group XXXV] Discriminator apparatus for ultra - high - frequency oscillations comprises a hollow resonator tuned to the mean frequency of the applied oscillations, means for picking up oscillations of opposite phase within the resonator and combining them with oscillations from the source, and detector means for receiving the combined oscillations. The apparatus may be used as a F.M. demodulator, or for stabilizing the frequency of an oscillation generator. Fig. 1 shows a F.M. demodulator in which received carrier from an aerial 1 is applied to a hollow resonator 4 tuned to the mean carrier frequency. Carrier in opposite phases is picked up by the loops 10, 10<1> and is combined with carrier supplied from the line 2 through a phase-adjuster 13 and attenuator 14 to the mid-point of the loops 10, 10<1>. Normally, the carrier from 13, 14 is in quadrature with that picked up by the loops 10, 10<1>, but as the frequency varies, this normal relation is departed from. The combined carriers are rectified in crystal detectors 15, 15' with balanced load resistances 18, and the differential output is applied through a transformer 17 and amplifier 19 to the signal reproducer 20. Thermally-responsive resistances arranged in a bridge circuit may replace the crystal detectors (Figs. 7 and 7a, not shown). In Fig. 8, the frequency of a generator 30, of the kind described in U.S.A. Specification 2,242,375, is held constant by applying its output to a resonator 4 arranged as in Fig. 1, and the combined oscillations are applied to detectors 22, 22<1>, connected as adjacent arms in a bridge circuit, the opposite arms of which are formed of variable resistances. An A.C. supply source 24 is connected across one diagonal, and output transformer 31 across the other. When the frequency deviates from its mean value, output from 31 is amplified at 32 and applied to the mid-point of the secondary coil of a transformer 34, the primary being energized from the supply source 24. The ends of the secondary are connected through oppositely-poled rectifiers 37, 37<1> and smoother 38 to the grid of a valve 41 which lies in the cathode lead of the generator 30, thus adjusting the accelerating voltage in the sense to restore the original frequency. A slower control of the beam current of the generator is effected by a grid 54 connected between resistances 52, 53 shunted by a triode valve 44. This valve has its grid connected to a potential-divider 45 shunted by a gas tube 49 and in series with a further resistance across the bus-bars 43, 46. A condenser 51 connects grid and cathode of the valve 44.

Title: Pellicle of non-fibrous regenerated cellulose
IPC: C08J7/056
Filed: 1959-01-16
Abstract: A pellicle or film of non-fibrous regenerated cellulose uniformly carrying at least 15% by weight of a substantially linear vinyl or vinylidene homopolymer or copolymer which is chemically and directly connected to the cellulose, is made by impregnating regenerated cellulose film, preferably in a wet swollen gel state, with an aqueous solution containing 1 to 10% of a free radical initiator based on the weight of the cellulose and contacting, under graft polymerization conditions, the activated film with one or more vinyl or vinylidene monomers until at least 15% based on the weight of the film has grafted thereon.  The monomers grafted on to the film may be acrylic acid, acrylonitrile, an acrylic ester in which the alcohol residue is obtained from methanol, octadecanol, dimethylaminoethanol, benzyl alcohol, or p-chloromethylbenzyl alcohol, vinyl or vinylidene chloride, methyl vinyl ether, acrylamide, isoprene, ethylene, butadiene, or chloroprene.  The grafted film may be after-treated to introduce new groups into the linear polymer chains, e.g. a film containing acrylamide units may be subjected to a Hofmann degradation to change the acrylamide units into amine units, or acrylonitrile units may be converted into -CH2-C(NH)-(NHOH) units by treatment with hydroxylamine, or units containing tertiary amines, may be quaternized, or ester units may be converted to alcohol units by hydrolysis.  The polymerization initiator may be cobaltic sulphate, ceric ammonium sulphate or nitrate, manganic pyrophosphate, NaClO2, Na5IO6, Mn2(SO4)3, MnCl3, NaBrO3, or KBrO3.  The monomers may be reacted with the film in the gaseous, liquid, or solid state.  The graft polymerization may be effected in bulk or solvent, or aqueous solution or emulsion. Prior to teartment, the cellulose film has had all solubles, including the glycerol plasticizer, removed.  Monomers exemplified are acrylamide, acrylonitrile, stearyl methacrylate mixed with ethyl acrylate, ethyl acrylate mixed with dimethylaminoethyl methacrylate nitrate solution, butyl acrylate mixed with ethylene glycol bismethacrylate, vinyl chloride, methyl acrylate and ethyl acrylate.  The films may be decorated, printed, or dyed, and they may be used as a packaging material or as an outer ply in the manufacture of plywood.  (see Group VIII).
